From 0843ba458439f38efdc14aa359c14ad0127edb01 Mon Sep 17 00:00:00 2001 From: Sourabh Jain Date: Wed, 8 Oct 2025 08:59:34 +0530 Subject: [PATCH] powerpc/fadump: skip parameter area allocation when fadump is disabled Fadump allocates memory to pass additional kernel command-line argument to the fadump kernel. However, this allocation is not needed when fadump is disabled. So avoid allocating memory for the additional parameter area in such cases.
